Anti-PRCP antibodies are used in the immunodetection of the protein prolylcarboxypeptidase. In humans, the canonical protein has a reported length of 496 amino acid residues and a mass of 55.8 kDa. Its subcellular localization is in the lysosomes. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the placenta, lung and liver. A member of the Peptidase S28 protein family, PRCP is known to be involved with carbohydrate metabolism and homeostasis and proteolysis. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include PCP, lysosomal Pro-X carboxypeptidase, angiotensinase C, lysosomal carboxypeptidase C, proline carboxypeptidase, and HUMPCP. PRCP gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some Prcp antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
